Natalie has $6 more than Emma. Joelle has thrice as much money as Natalie. They have a total of $189.
- How much money does Natalie have?
- How much money does Joelle have?
(a)
Amount that Natalie has = 1 u
Amount that Emma has = 1 u - 6
Amount that Joelle has = 3 u
Total amount that they has
= 1 u + 1 u - 6 + 3 u
= 5 u - 6
5 u - 6 = 189
5 u = 189 + 6
5 u = 195
1 u = 195 ÷ 5 = 39
(b)
Amount that Joelle has
= 3 u
= 3 x 39
= $117
Answer(s): (a) $39; (b) $117
